Dear Jack, this code has not yet been fully ported to deal.II-v9.3.0. I realize that I am using the dealii:v9.2.0-focal docker container in my github actions workflow. On this container, the code compiles. If you want to compile inside the dealii:v9.3.0-focal container you need to add
SET(CMAKE_CXX_STANDARD 20) to line 13 of the main CMakeLists.txt file. This worked on my end. Best wishes, Sebastian jack urombo schrieb am Mittwoch, 6.
